Hydrophilic Coated Medical Single-Use Sterile Ureteral Stent

The product consists of a stent catheter and a pusher tube. The stent catheter is classified into three types: single pigtail stent catheter, double pigtail stent catheter, and flared single pigtail stent catheter. Some models are equipped with accessories such as hydrophilic coating, through-hole metal beads, traction wire and nitinol guidewire.
The product is indwelled between the kidney and the bladder to provide support and drainage for the human ureter, and is used for the treatment of ureteral obstruction and stricture. The indwelling time in vivo is less than 30 days.

Core Applications
·Support & Drainage: Indwelled between the kidney and the bladder to provide essential support and ensure smooth urine drainage through the ureter.
·Obstruction Treatment: Primarily used for the treatment of ureteral obstruction, stricture, and as a scaffold during the repair of ureteral injuries.
·Post-operative Care: Highly recommended for post-calculi surgery drainage to prevent complications such as ureteral adhesion or secondary stenosis.

Product Features
·Versatile Anatomical Designs: Available in single pigtail, double pigtail (Double-J), and flared single pigtail configurations to meet diverse clinical and anatomical requirements.
·Advanced Hydrophilic Coating: Select models feature a hydrophilic coating that significantly reduces friction during insertion, minimizing mucosal trauma and improving patient comfort.
·High Biocompatibility: Crafted from medical-grade polymer materials, the stent is sterile, pyrogen-free, and designed to minimize irritation and encrustation.
·Comprehensive Accessory Kits: Can be equipped with nitinol guidewires, through-hole metal beads, pushers, and traction wires for precise endoscopic placement.
·Optimized Indwelling Safety: Specifically designed for a safe in-vivo indwelling time of less than 30 days, aligning with standard clinical recovery protocols.
